The Best-Selling Net-a-Porter Skincare Products in London, NYC, and L.A

Net-a-Porter has become one of the heavy hitters when it comes to respected beauty purveyors—right alongside Sephora, Ulta, and the like. The site offers a superbly curated set of products for those devoted to beauty knowledge and prestige (with a few products for less than you'd expect, like a French drugstore moisturizer). It has everything from Charlotte Tilbury to La Mer and Tata Harper to Embryolisse, covering your favorites and offering a few things you never knew you needed.

The interesting thing, though, is that its best-selling products differ in various markets based on the needs and personalities of those who reside there. For example, the beauty products that sell best in New York are meant for efficiency, while those in L.A. are a bit more glamorous (courtesy of the "red carpet influence") or natural (à la the "clean beauty" set). Then there's London, where beauty connoisseurs look for luxe, thoughtful skincare choices with a focus on innovation. Below, find the 15 best-selling products in each region and purchase accordingly.

New York

This cult-favorite, 100% natural serum is Vintner's Daughter's only SKU—yes, the brand focuses entirely on this one product. Because it's that good. It has over 22 active ingredients (including avocado oil, calendula extract, rose, lemon peel, rosemary leaf extract, neroli oil, lavender, and turmeric root oil) to help fight signs of aging as well as stimulate cellular turnover, maintain elasticity, brighten, oxygenate, and reverse free-radical damage. All you have to do is place six to eight drops in the palm of your hand and rub them together to warm and activate the formula.

Formulated as her own private formula for years, Charlotte Tilbury's Magic Cream was originally used to moisturize the models backstage ahead of many runway shows. It worked so well she decided to package and sell it to the rest of us. It instantly rehydrates dull, stressed, or hungover skin; plumps with hyaluronic acid; nourishes with bio-nymph peptides; and improves elasticity in your skin, while vitamin E, rose hip, and camellia oils add moisture and dewiness. It also contains rose water and organic aloe vera to soothe, de-puff, and purify your skin.

Of course, the French moisturizer in the instantly recognizable blue and white tube made the list. The best part? According to makeup artist Carissa Ferreri, the appeal here is all about the finish. "It moisturizes the face while emphasizing a beautiful glow, but it never looks greasy," she says. Because of the silky consistency, it's also a super-versatile product. Ferreri uses it on her clients as a moisturizer but also mixes it with medium- to fuller-coverage foundations to create a tinted moisturizer.

She continues, "I especially like to use it with a cotton swab to clean up any eye makeup residue under the eye for a clean canvas prior to foundation and concealer."

No skincare list is complete with La Mer's original, highly coveted Moisturizing Cream. You only need a tiny bit (it's super thick) to rub between your fingers and apply to parched skin. It has that aforementioned Miracle Broth, which is special not because of the ingredients but the way they're combined (a process called biofermentation), which is incredibly nutrient-rich and quickly penetrates, replenishes, and quenches your skin.

L.A

This skincare set makes you feel quite like a chemist. It includes five vials of pure, highly concentrated vitamin C. It works to protect and treat pigmentation and is meant to be mixed with your favorite serum or moisturizer. All you have to do is take half the reservoir cap and sprinkle the powder-cream formula into the palm of your hand and mix with your chosen skincare product. Then, apply it to your face and expect dramatically brighter skin.

Carla Oates, the founder of Australian company The Beauty Chef, laments that "beauty begins in the belly," and she's not wrong. To drive that point home, she created this bio-fermented probiotic concentrate to target fine lines, firm your skin, and aid in regular skin maintenance (i.e. bring about more radiance, plumpness, and collagen production). It combines organic maqui berry, açai, papaya, blueberry, goji berries, and pomegranate powders with zinc, vitamin C, and grape-seed extract to leave your skin smoother and your body rich in prebiotics and probiotics.

It's dairy-, sugar-, and gluten-free and offers 33 servings per container. All you have to do is mix it in with 200 milliliters of water and enjoy.

What's an L.A.-themed roundup without a little alternative wellness, right? Based out of Silver Lake and Venice, the brand creates "dusts" (and now supplements) that draw on the healing and transformative powers of herbs, plants, and minerals. This one, Moon Juice's medicinal-grade Beauty Dust, boosts the production of collagen and silica to improve your skin's elasticity. Just stir it up in your morning coffee, a smoothie, or some almond milk to get your dose of goji, rehmannia, pearl, and Schisandra.

London

The first time I tried these ampoules was on a trip to Paris. Post-plane, my skin was super dehydrated and looked, well, sad. I unwrapped the packaging (it was a product I had thrown into my bag without thinking), curious to see what they could do. Already a huge fan of Dr. Barbara Sturm's products, I had high expectations. See, it contains an active complex of short- and long-chain hyaluronic acid so as to provide both short- and long-term effects on your skin. Blended with the antioxidant purslane, the formula immediately firms and hydrates your complexion, and, over time, diminishes fine lines and nourishes down deep in your dermal layers.

Snap open an ampoule, pour the fluid into the palm of your hand, and gently pat it into your skin prior to applying moisturizer. You'll be so thankful you did.

These cleansing pads are infused with rose water and wild mint (yum) and specifically designed to be helpful while in-transit. For a city like London, it makes sense. The high concentration of natural actives and plant oils work to repair, soothe, and gently moisturize as it removes impurities from your skin and restores a healthy pH balance.

While it's technically a makeup product, Charlotte Tilbury's air-light foundation illuminates, smoothes, hydrates, and minimizes pores like skincare. It kick-starts collagen production, includes an SPF of 15, and is entirely oil-free.

Founders and former athletes Charlie Turner and Lee Forster spent years trying to find the right nutritional supplements. When they couldn't, they decided to formulate their own. These capsules each work to break down fats and generate metabolic energy. They're made with matcha green tea to reduce fatigue (but save you from that jittery caffeine feeling).
